He added: “Both players look happy and overall I hope the situation can be turned round, but at the moment we are not close enough to announce anything. Talks are going well.”

However, Ozil’s agent Dr Erkut Sogut said earlier in the week that the Germany international wanted to play in the Premier League for another two to three years and that talks with Arsenal ‘are going in a positive way’.

“I have always said that the fact we didn’t find an agreement last year doesn’t mean the player will necessarily leave.

“Both players looked happy here and overall I hope the situation can be turned around.

“At the moment we are not close enough to announce anything.”

Sanchez will be dealing with both fatigue and the disappointment of missing out on next summer’s tournament in Russia, and Wenger said he will have to gauge the player’s physical and mental state before deciding whether to play him at Watford.

“I will have to speak to him,” Wenger said. “It was a very physical game [against Brazil]. Mentally I will have to assess the situation when he comes back tomorrow.”

But Wenger said that Sanchez’s disappointment will not have a long-term effect on his commitment to Arsenal this season.

“I don’t think [it will]. I believe that he, like [Wales’] Aaron Ramsey, they are winners. They want to focus on winning things,” Wenger said. “The World Cup is a stimulant, I don’t deny that, but when you don’t have it you focus on your club and what you can achieve with your club.”
